PRINTING DEVICE.

Application filed April 27,

To all whom it may concern.'

Be it known that 1, MICHAEL BoNsninos, a citizen of(` the United States, residing at Sain Francisco, in the county of San ifrancisco and State of California, have invented new and useful Improvements in .@rinting` Devices, of which the following is a specification.

This invention relates to a printing device. and is particularly concerned with that type of machine shown in my Patent No. 1,367 ,939, entitled Marking device, and granted February 8, 1921.

Tt is the principal object of the present invent-ion to provide a simple stamping device which may be inked and operated when depressed, and which structure is compact in its arrangement and direct action.

The present invention contemplates the use of a fixed support carrying a depressible head, said head embodying a pluralityv of sets of stamping elements arranged to 1ace-selectively disposed in printing position, and movable means for positioning a pressure table and inking` pad beneath the head.

rThe invention illustrated by way of example in the accompanying drawings, in which:

Figure 1 is a view in vertical section and elevation showing` the assembled device with which the present invention is concerned.

Fig. 2 is a view in side elevation showing the yieldable support for the head and disclosing. thevink pad arrangement in section.

Fig. 3 is a fragmentary view in elevation showing the arrangement of the type.

Referring more particularly to the drawings, 10 indicates a supporting` frame which may be rigidly secured to a bench or other fixed support. This frame is formed with an upper extending portion 11 having bosses thereon. Guide rods 13 entend through these bosses and are circumscribed by coil springs la. The guide rods project through openings in lugs 15 which are carried at the back of a printing head 16.

The head comprises a pair of vertical side plates 17 formed with openings to receive transverse shafts 18, 19, 20 and 21. The shafts are arranged in parallel relation to each other and are in vertical alignment. The lower shaft carries a plurality of sprocket wheels 22, all of equal diameter and freely mounted upon the shaft 21. The shaft 2O carries a pair of sprockets of equal Specification of Letters Patent.

diameter, as indicated at 23 and 2a. The sprocket 23 is keyed to the shaft 20, while the sprocket 241- is freely mounted thereon. The sprocket 211- is formed with a hub 25 extending outwardly through one of the side plates 17 of the head. An index finger 26 is secured upon the outwardly eX- tending end of the hub, and makes it possible to adjust the sprocket 24 as desired. An index finger 27 is secured on the opposite end of the shaft 20, thus permitting the two sprockets 23 and 24 to be independently adjusted and set relative to dials inscribed upon the side plates. The shaft 19 which is disposed .above the shaft 2O carries sprockets 23 and 29. These sprockets are arranged as previously described for the sprockets of shaft 20. That is, sprocket 23 is keyed to the shaft 19 and sprocket 29 is freely mounted thereupon. This sprocket is also formed with a hub 25 extending through the side of the head to receive an index finger 26. The shaft 18 is fitted with sprockets 30 and 31, similarly arranged. The sprockets upon the shaft 2O are arranged close to each other to receive sprocket chains 32 of the two` inner-most sprockets on shaft 21. The sprockets 28 and 29 on shaft 19 are spaced apar to receive the next succeeding sprocket chains, and the sprockets 30 Aand 31 are arranged to receive the outermost sprocket chains.

The sprocket chain is more clearly shown in Fig. 3 as comprising links 32 pivoted to blocks 33. These blocks are in reality metal type, which may be moved to printing positions relative to thetable of the machine by rotation of `the sprockets.

Slidably mounted upon the frame 10 and adapted to move transversely of the frame in a horizontal plane is a table 34. This table is formed with a flatprinting face 35 and a recessed portion 36. The recess carries an inking pad 37. The table may be moved to and fro so that the type may be inked, and thereafter the printing face 35 disposed beneath the type to receive an object against which the type are impressed. The printing head 16 may be forced downwardly by the pressure of the hand against the top of the head or by a foot pedal 38 carried at the lower end of a rod 39. This rod is secured to the head by a yoke e0.

In operation of the present invention, the various sprockets may be rotated by the ngers 26, thus insuring that' certain type 33 Will be disposed in alignmentand in printing relation beneath the head li6. lt will be understood that the type blocks 33 mayl carry letters, numerals, Words, or phrases. W ien the type have been properly set the head may `be forced downwardly to bring the type into register with the inlring pad 37. lvl/hen pressure is released from the head the springs lll Will expand and litt this member, after which the table 3i `willbe moved in the direction ci the arrow ayto dispose the printing face 35 beneath the type.

It Will thus be seen that the device here disclosed provides simple and compact means for setting and printing various characters. y

While l have shown the preferred form of my invention, it will be understood thatl variouschanges might be made in the combination, construction, and arrangement of parts, by :those skilled inthe art, Without departing from the-spirit of the invention, as claimed. f

ll'aving thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A printing device comprising a supporting frame, a printing head vertically slidable on said trame, a plurality of sets of type carried Within the head, means for selectively disposing type of the various sets in a printing position, a ytable disposed beneath said head comprising a flat printing face and an inking face, and a mounting for said table whereby depression of the. head may :torce the set type against the ink pad vor an art-icle o-n4 the printing tace.

2. A printing device comprising a supporting frame, a printing` head vertically slidable on said rame,.a plurality offsets of type carried Within the head, means for selectively disposing type of the various sets in a printing position, a table disposed beneath said head comprising a fiat printing face and an inlzing face, a mounting for said table whereby depression of the head may force the set type against the ink pad or an article on the printing face, and means for yieldably'. supporting the printing 'head 'in an inoperative position. 3. A printing device comprising a fixed vertical iframe having' guides formed at opposite sides thereof, a printing head having guide rods slidable in the said guides on the frame, and springs associated zWith said rods for retaining the head in its Lipper- `most position, a zplurality ofsets of type carried by the head, and means for selectively disposing type ot the various sets in a lprinting position, and a movable table having an inlring pad and a ,printing surface, amounting for said table whereby [depression of the head may force the' set type against the ink pad or an article on the printing face.

4. A device of the character described comprising a vertical frame member having vertically disposed guide members vformed at opposite sides thereof, a printing head having guide rods slidably disposed in saidvguides on the frame, expansion springs interposed between the guides and the head for retaining the head in its uppermost position, a plurality of type members carried by the head, means for selectively disposing various of the type ina ,printing position, a movable table having an inking pad and a printing plate, a mounting for said table whereby depression of the head may force the set type against the pad or an article on the plate, anda toot pedal connected with the .head for operating the same against the pad or the plate.
